This is straightforward to do: just discover the lock icon before the URL during the address bar and drag that towards the bookmark toolbar With all the mouse. In case you locate the bookmark entry way too very long, you may appropriate-simply click it to edit the textual content, e.g. utilizing "RP Enc" as an alternative to "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Certainly, it is vitally attractive that a supplied crystal good quality is developed constantly, Whilst distinctive laser layouts may have a special sensitivity to product parameters.
g. a skinny disk. As An additional illustration, Q-switched lasers attain a better inhabitants density within the upper laser stage and are as a result extra sensitive to quenching results and Strength transfer procedures; hence, a reduce doping density is usually appropriate for these devices. For high-electrical power lasers, decrease doping densities in many cases are utilized to Restrict the density of heat technology, although slender-disk lasers work greatest with very doped crystals. Several laser items don't get to the whole effectiveness likely due to the fact this read more sort of details haven't been correctly labored out.
A couple of laser crystal elements are already shown in which some saturable absorber product is incorporated for passive Q switching of a laser.
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is apparent that distinct programs cause incredibly unique prerequisites on laser attain media. For this reason, a wide array of various crystals are utilized, and creating the proper option is important for setting up lasers with ideal effectiveness.

For numerous reasons, composite crystals are getting to be well known. These Possess a spatially varying chemical composition and may be manufactured with Distinctive shapes.
Utilizing our promotion package deal, you could Show your brand, further under your products description, and these will been noticed by lots of photonics experts.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
